Abstract

The invention relates to a lithium battery pack maintenance and performance detection apparatus, which comprises a charge and discharge machine unit used for connecting to a lithium battery pack, an equalization unit used for performing equalization of batteries in the lithium battery pack and a local monitor unit, wherein the local monitor unit is connected to the charge and discharge machine unit through sampling and controlling; and the local monitor unit and the equalization unit are connected to a CAN bus. The lithium battery pack maintenance and performance detection apparatus has strong function, and can realize the functions of battery pack equalization, monomer internal resistance testing and capacity testing.

Description

technical field [0001] The invention relates to a lithium battery pack maintenance and performance detection device, which belongs to the field of electric vehicles and new energy power batteries. Background technique [0002] The power battery pack is the main energy carrier and power source of various electric vehicles, and it is also the main component of the cost of the electric vehicle. Its life directly affects the cost of electric vehicles. [0003] The battery packs on electric vehicles are generally used in series with multiple single batteries. The charging and discharging process of batteries used in series is much more complicated than the charging and discharging process of single batteries. The power required for high-speed driving is More than 40kW, so the current when the battery is discharged is generally very large. In order to be fully charged in a short time when charging, it also requires high current charging, which will cause inconsistency of the batte...
